RAID6 Array needs to be manually reassembled after every reboot

  • Hi,

    I'm Running OMV 3.0.99 on a Odroid XU4 with 4 x 2TB in RAID6 through a USB3 interface (JMicron). Every time I reboot I get an email reporting a degraded array and the array fails to mount automatically. However If I do the following the array mounts without problems:
    mdadm --assemble /dev/md0 /dev/sd[abcd] --verbose --force

    Sometimes after doing this one of the drives will be missing and I have to add it manually:
    mdadm /dev/md0 --add /dev/sda

    The array is reported to be clean and runs normally after doing this. No SMART errors either.

    Any ideas?
